我在这里有点困惑，我有一个数组bytes，我将其转换为 astring 然后拆分string并将拆分添加到 anArrayList 然后将其添加ArrayList到 aListView中。它以前可以工作，但现在不行，我不知道为什么。

//bytes to string.
string str = Encoding.Default.GetString(bytes);

// clear arraylist and listbox.
ItemDetails.Clear();
listBox1.Items.Clear();

// split the string and add the split into the arraylist.
ItemDetails.AddRange(str.Split(new string[] { "\r\n" }, StringSplitOptions.RemoveEmptyEntries));

// Add arraylist into listbox. It throws the generic error here:
listBox1.Items.AddRange(ItemDetails.ToArray());

我知道这里没有很多信息，所以如果您需要任何其他详细信息，请告诉我。

尝试重新创建控制。可能 Initialize() 中的设计器代码已损坏。看起来列表框无法更新项目的宽度，因为测量字符串失败。

您能否从 Initialize 中发布描述 listBox1 的代码？
